Natural and synthetic materials in fine granular form incorporated in buflng compounds,
attached to cloth or paper, or suspended in liquids or rubber. Generally sold in various
abrasives
grades from very coarse to very fine. Paper and cloth-backed versions may be identified by a
numerical system (coarsest -50 - 80 - 180 - 240 - 320 - 400 - 600 - 1000 1500 - finest).
A colorless gas used under compression to produce high temperatures when mixed with air
acetylene
or oxygen.
Any agent that will block the corrosive action of acid, used mainly in etching. Some of these
acid resist
are: asphaltum, varnish, beeswax, and dental wax.
The result of combining two or more metals, or a metal and a chemical element. For example,
alloy
sterling silver is an alloy composed of pure silver and copper.
aluminum
A bluish, silver-white metal, noted for lightness and resistance to oxidation. Usually this metal
is sold in alloys designed to improve ditterent aspects of the metal, such as its ability to be
anodized, or its strength. (Al, mp 1220° F)
American Standard gauge
A flat disk of metal with notches graduated in size and numbered 1 (thick) to 36 (thin). Most
non-ferrous metals are measured using this gauge. (also Brown and Sharpe Gauge)
A heat treatment of metal that realigns its crystalline structure to its natural, more malleable
state. This also removes stresses created in manipulation during the work process such as annealing
bending, raising, forging, rolling, etc.
annealing pan
A circular pan that supports the workpiece while heating with a torch. These pans are usually
filled with pea pumice and designed to be rotated as heat is applied.
anodizing
The electrochemical application of an oxide film over aluminum or titanium causing its surface
to become harder, abrasion and corrosion-resistant
anvil
,Usually a heavy supporting surface over which metal is hammered. Many have a traditional
form composed of a squarish base, flat top, and tapered horn.
beaker
A cylindrical heat-proof glass container for warming liquids.
bench pin
A wedge-shaped block of hardwood attached to a bench to support work while sawing or
filing.
bench plate or bench block
A thick slab of hardened steel used to support metal during flattening and texturing processes.
bevel
The angle that one surface makes with another when they are not at right angles.
brass
An alloy of copper and zinc in variable proportions which is commonly reddish yellow to rosy
orange in color. Some common alloys are: yellow (65 Cu/35 Zn, mp 1660° F), red (85 Cu/15
Zn, mp 2200° F). Usually, but not always used in wrought forms such as sheet and wire.
A brownish red-yellow alloy of copper and tin. Usually used with casting processes. (Cu 90/Sn
10, mp 2250° F)
, bronze
A large natural gas flame with compressed air added until there is no blue cone. This large
brushing flame
bushy flame is most often used to anneal or gradually heat metal.
burr
(1) A sharp-tipped projection.
(2) A rotary steel cutting tool generally used in a flexible shaft machine.
An edge-to-edge fit between two pieces of metal butt seam
capillary action
The force that causes a liquid to be raised against a vertical surface, or pulled into small
crevices.
chasing hammer
a lightweight hammer with a springy pistol-grip handle, and a head that has one large circular
striking surface (used for striking chasing punches), and a ball peen.
Usually the natural, chemical, or heat patination of metal. Oxidation, plating, and anodizing
coloring
are a few of the methods used.
A metal that is reddish in color, ductile, malleable, and very tenacious. A good conductor of
copper
heat and electricity. (Cu, mp 1981° F)
